Well, I was reading this post about "Ubuntu 9.04 Samba Server Integrated With Active Directory" http://www.howtoforge.com/comment/reply/4694#comment So, I´m facing this situation: I have a Ubuntu 8.04 (server kind), running samba, as a PDC and a file server too. The pc clients are all Windows XP/Vista and some 7. The users sharing folder/files through the ubuntu server. Few weeks ago, we get a new PDC server, this time with a Windows 2008 Server. The ubuntu server will be just a fle server. I´ve already created the ad user accounts . So, I need to make the ad users access the shares on the ubuntu file server. How? Based on this, that howtos could help me? Thanks any help!
